Product Description
ECST1V1308 SMT Current Sense Transformer
The ECST1V1308 is an SMT current sense transformer designed for high-frequency applications. It features a very low DC resistance and a wide selection of turns ratios, making it suitable for precise current sensing up to 15 A. Its compact EE8.3 SMT package and broad operating temperature range (-40 C to +125 C) make it ideal for demanding environments. This transformer is engineered for applications such as switching power supplies, feedback control, overload sensing, and load drop/shut down detection.
